Washington: Sea levels rose faster in the past century than during the previous 27 centuries due to man-made global warming, a group of scientists has said in an alarming report.

Global sea level rose by about 14 centimeters, or 5.5 inches, from 1900 to 2000, the scientists said in a latest report, adding that without global warming, global sea level would have risen by less than half the observed 20th century increase.

"The 20th-century rise was extraordinary in the context of the last three millennia -- and the rise over the last two decades has been even faster," said Robert Kopp, the lead author and an associate professor in Rutgers' Department of Earth and Planetary Sciences.
